Assuming the kittens on the stairs all have the same mass, which kitten has the most gravitational potential energy? Question 5 options: kitten 1 kitten 2 kitten 3 kitten 4 kitten 5

Answers

Answer:

Assuming 5 stands above all of them.

5>4>3>2>1

Explanation:

As gravitational potential energy is the measure of energy in a body due its position from the earth surface so kitten 5 is high from all others so it will have the highest potential energy.

Gravitational Potential Energy = mgh

m=mass

g= constant for all.

h= it is varying in this case.

Let us assume height of kitten 5, 4, 3, as 5m, 4m,3m so on

Gravitational Potential Energy (5) = mg5

Gravitational Potential Energy (4) = mg4

So the kitten which is at the top will have the highest Gravitational potential energy.

A piece of copper (c = 0.385 joules over grams times degrees Celsius) undergoing a temperature change from 150°C to 225°C absorbs 3,500 joules of energy. What is the mass of the piece of copper? Express the answer to the nearest whole number. grams

Answers

The mass of the piece of copper, to the nearest whole number is 121 grams.

Given the following data:

Specific heat capacity of copper = 0.385 J/g°CInitial temperature = 150.0°CFinal temperature = 225.0°CQuantity of heat = 3,500 Joules

To calculate the mass of the piece of copper, to the nearest whole number:

Mathematically, quantity of heat is given by the formula;

[tex]Q = mc\theta[/tex]

Where:

Q represents the quantity of heat.m represents the mass of an object.c represents the specific heat capacity.[tex]\theta[/tex] represents the change in temperature.

Making "m" the subject of formula, we have:

[tex]m = \frac{Q}{c\theta}[/tex]

Substituting the given parameters into the formula, we have;

[tex]m = \frac{3500}{0.385(225-150)}\\\\m = \frac{3500}{0.385 \times 75} \\\\m = \frac{3500}{28.875}[/tex]

chimpanzee cells have 48 chromosomes. how many sister chromatids are present in a chimpanzee cell in the g2 phase of the cell cycle?

Answers

Answer:

Well, since there's two identical chromatids in each chromosome. Therefore, 48 times 2= 96, so chimpanzees have 96 chromatids in each chromosome during the g2 phase of the cell cycle.

         One of a chromosome's two identical halves that has been replicated in preparation for cell division is known as a chromatid. The centromere, a constrictive area of the chromosome, is where the two "sister" chromatids are linked.

How do chromatids and chromosomes differ?

         A chromosome is a piece of genetic material that possesses all of an organism's qualities and traits. "Chroma" and "Soma," which are derived from Greek and mean "color" and "body," respectively. Chromatids, the name for the pair of identical strands that make up a chromosome, are now understood.

            Role of Chromatids  In preparation for cell division, it permits cells to store two copies of their data. This is crucial to ensuring that daughter cells carry the entirety of the DNA from the parent cells and are strong, healthy, and completely functional.

          The chromosome is decondensed and only has one chromatid (long and string-like). DNA is duplicated. Currently, the chromosome comprises of two sister chromatids that are joined together by cohesin proteins.

         Each cell contains 46 unique chromosomes. Each cell contains 92 distinct chromatids and a total of 46 chromosomes following replication.

which statement best explains the difference between polar and nonpolar covalent bonds?

Answers

Answer:

Nonpolar covalent bonds involve two atoms that have equal electonegativity whereas polar covalent bonds involve two atoms that are unequal in their electronegativity.

Explanation:

Polar covalent bonding is a type of chemical bond where a pair of electrons is unequally shared between two atoms.If the electronegativity of two atoms is basically the same, a nonpolar covalent bond will form, and if the electronegativity is slightly different, a polar covalent bond will form.

A covalent bond is a force that joins two atoms of non-metallic elements to form a molecule. Atoms share pairs of electrons from their most superficial layer (called the valence layer) to achieve the stability of the molecule that has been formed with the bond and thus comply with the octet rule.

On the other side, electronegativity refers to the tendency of the atom of a given element to attract electrons.

So, the covalent bond between two atoms can be polar or nonpolar.  

Polarity depends on the difference in electronegativity of the joining elements. The greater the electronegativity difference, the greater the polar character of the bond. The most electronegative element will be the one that most strongly attracts the shared electrons, then a negative partial charge will be generated on said element, while a positive partial charge will be generated on the other element (less electronegative).

Finally, nonpolar covalent bonding occurs when pairs of electrons are shared between atoms that have the same or very similar electronegativity, favoring an equitable distribution of electrons.

In summary, the correct answer is: Nonpolar covalent bonds involve two atoms that have equal electonegativity whereas polar covalent bonds involve two atoms that are unequal in their electronegativity.

a rock falls for 1.43 seconds. how far did it fall?

Answers

The Answer is 10.03 m

Explanation:

Given,

time =1.43 s

distance =?

acceleration= 9.81

Now by the formula

s=ut + 1/2 gt^2

s= 0× 1.43 +1/2 (9.81)×(1.43)^2

s= 10.03 m

therefore distance = 10.03 m

The rock fell approximately 10.02 meters in 1.43 seconds in a vacuum with an acceleration of [tex]\( 9.80 \, \text{m/s}^2 \)[/tex]

To find the distance the rock fell, we can use the formula for distance traveled by an object in free fall:

[tex]\rm \[ \text{Distance} = \text{initial velocity} \times \text{time} + \frac{1}{2} \times \text{acceleration} \times \text{time}^2 \][/tex]

Given that the rock is falling from rest, the initial velocity u is 0 m/s. The acceleration due to gravity g is [tex]\rm \( 9.80 \, \text{m/s}^2 \)[/tex], and the time the rock falls t is 1.43 seconds. Plugging these values into the formula:

[tex]\[ \text{Distance} = 0 \times 1.43 + \frac{1}{2} \times 9.80 \times (1.43)^2 \]\[ \text{Distance} = 0 + \frac{1}{2} \times 9.80 \times 2.0449 \]\[ \text{Distance} = 0 + 10.0191 \]\[ \text{Distance} = 10.02 \, \text{meters} \][/tex]

So, the rock fell approximately 10.02 meters in 1.43 seconds in a vacuum with an acceleration of [tex]\( 9.80 \, \text{m/s}^2 \)[/tex]. The correct answer is indeed 10.02 meters.

what would be the outcome of the processes shown above if the mrna never moved outside of the nucleus?

Answers

Answer:See below

Explanation:

The process of protein synthesis initiates with the transcription process in the nucleus and continues with the translation process in the cytoplasm. If the mRNA never left the nucleus, the translation would not be possible.

-------------------------------------

The protein synthesis process involves transcription and translation.

Transcription:

Transcription is the copying process of the DNA section for the desired protein occurs.

It happens in the nucleus, where the template DNI strand is read in direction 3´→ 5´ to build the mRNA molecule in direction 5´→ 3´.

Once the transcription is over, the new mRNA molecule leaves the nucleus and goes to the cytoplasm.

Translation:

Translation occurs in the cytoplasm when mRNA meets a ribosome.

rRNA and tRNA read mRNA in the direction 5´→ 3´ to build the protein.

While the ribosome reads mRNA strain from its 5´ extreme to 3´, tRNA adds the correct amino acids to build the polypeptide.

Protein growth initiates in the AUG start codon -Metionin-, and ends when reaching either of the stop codons UAA, UAG, UGA.

If the mRNA does not move outside of the nucleus, the translation process is not possible. Only transcription would occur, but no translation. Protein synthesis could not be accomplished.

Answers

Based on meteorological information El Nino generally reduces the number of hurricanes formed in the Atlantic ocean.

This is because the impact of El Nino quells the Atlantic hurricane effect. This is done by raising the quantity of sinking motion and improving atmospheric resilience.

On the other hand, La Nina results in a more active tornado season.

This is because the La Nina effect pushes the jet stream to move towards the north, and subsequently, this effect reduces around the Pacific side.

Excessive rainfall can lead to crop damage and landslides in California.

This is because continuous rainfall at a certain level in California leads to erosion which can damage crops. Subsequently, continuous rainfall of about two weeks can turn erosion into landslides in California, particularly the southern side.

Hence, in this case, it is considered that different climatic conditions affect the physical environment of humans.
